Patent GB-449898-A (GB)
Title: Improvements in or relating to synthetic resins of the urea formaldehyde type
IPC: A45C13/03
Filed: 1934-11-02
Abstract: Urea-formaldehyde resins are prepared by condensing one molecular proportion of urea and/or thiourea or a mono-substituted urea with 1,5 to 2,5 molecular proportions of formaldehyde or one of its polymers in the presence as catalyst of methylamine, ethylenediamine, an amylamine, a propylenediamine or a phenylenediamine, or of a reaction product thereof with formaldehyde.  The catalyst is preferably employed in the proportions of 1 to 5 grams per gram molecule of the urea, and may be removed from the product by washing or rendered inert by the formation of addition products, e.g. with ethylene chlorhydrin, ethyl oxalate, mercuric chloride, barium chloride or acids.  Weak acids, such as carbonic, stearic and carbolic acids may be present, either as such or in the form of salts of the bases, in the reaction mixture.  After resinification, the product is mixed on hot rolls with a fibrous filler, such as cotton flock, alpha-cellulose pulp or paper pulp, to form a moulding composition, or made up into a varnish for impregnating or coating purposes with a solvent such as aqueous methyl alcohol, ethyl lactate, benzyl alcohol, or those sold under the Registered Trade Marks of "Cellosolve" and "Hexalin."  Laminated materials may be made from paper impregnated or coated with the resin.  Examples are given of the condensation of (1) urea with paraformaldehyde in the presence of ethylenediamine, (2) a mixture of urea and thiourea with aqueous formaldehyde using methylamine as catalyst, or a mixture of n-amylamine and calcium carbonate; (3) urea with aqueous formaldehyde in presence of a solution of methylamine saturated with carbon dioxide; in each case the product is kneaded with cotton flock and rolled on heated rolls.  Specifications 271,264, 302,737, [both in Class 2 (iii)], and 345,845 are referred to.  The Specification as open to inspection under Sect. 91 describes also the use as catalysts of hydroxylated amines such as triethanolamine, monosubstituted amines including hydroxylamine, monosubstituted diamines, aromatic amines such as aniline, aldehyde-ammonias made by reacting ammonia with a higher aldehyde such as benzaldehyde, and hexamethylenetetramine.  The proportions of the reactants are not restricted.  Mixtures of ureas with any amide that will react with aldehydes, e.g. acetamide and p-toluenesulphonamide, may be used, whilst the formaldehyde may be replaced wholly or in part by aldehydes or ketones which resinify or decompose in the presence of strong alkalies, e.g. paraldehyde, benzaldehyde and acetone, or by alcohols which are unstable in the presence of alkalies, e.g. benzyl alcohol and hydroxybenzyl alcohol.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to Specification 302,737.
